SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 299,335, dated May 27, 1884.

Application filed September 22, 1883. (No model.)

' showing the holder applied. Fig. 2 is another view of the same, showing the position the holder assumes when the sash is being raised or lowered. Figs. 3 and 4 are views of the holder.

The holder consists of a pivoted metal bar,

A, hanging vertically by a pin or screw, 1),,

passed through it at a point above its center. The pin serves as a pivot, and the longest end of the bar hanging down will cause it to maintain a vertical position. At each end of the pivoted bar a rubber or other elastic roller, 0, is attached by a stud, d.

The letter E designates a window-frame; F, the sash; g, the usual retaining-strip. The pivot-pin b enters the retaining-strip or window-case, and should be in such position that when the sash F is down, as in Fig. 1, both. rubber rollers will bear and press against the front face of the sash. This pressure against the sash of the two rubbers, located at points remote from each other, (in practice the rubbers should be twelve inches apart,) serves to press both the top and bottom of the sash, and thereby effectually prevents rattling. Then the arrangement of the two rubber rollers on one bar, which is pivoted at a point between them, enables the sash to be easily raised or lowered notwithstanding the fact that the rubbers exert considerable pressure against the sash when the latter is down.

In raising the sash, the rubber-rollers at first turn on their axes, (the studs (1,) which are at right angles with the front side of the bar. \Vhen the sash is raised above the lower roller. the bar A swings on its pivot, and thereby all pressure of both rollers is at once removed. WVhen lowering the sash, the upper roller is forced thereby slightly to one side-that is, away from the sash, as shown in Fig. 2, and the same movement throws the lower roller in the opposite di1'ectionthat is, under the sash. Now, upon continuing to lower the sash, the lower roller will be forced outward and will bear against the sash, and thereby the upper roller is also brought against it. Thus the device is automatic in its action.

Having described my invention, 1. claim and desire to seen re by Letters Patent of the United States- A sashholdcr consisting of a vertical bar pivoted to the window-case, and provided with two rollersone above and one below the pivotthe said rollers turning upon axes at right angles with the front side of the bar, whereby the rollers may bear against the front face of the sash, as set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

GILBERT O. BOLGIANO.
